Self-leveling mortar is a kind of polymer-modified cement that has high flow property, which is typically applied to interior big floor coverings, such as large shopping malls, supermarkets, industry workshops and etc.SLEOCHEM cellulose ether plays an important role in self-leveling to achieve a smooth and flat surface with the key properties of anti-cracking, anti-shrinkage, preventing segregation, lamination, bleeding, etc.
Self-leveling mortar includes cement-based self-leveling mortar, self-leveling mortar, leveling mortar, etc.
It is slightly expanded by a scraper to give a high level base surface. It can be used as a decorative surface and as a wear-resistant base layer.
it is a dry mixed powder material composed of a variety of active ingredients, which can be used by mixing water on site.
The high leveled base surface can be obtained after being slightly expanded by the scraper. The fast hardening speed and fast and simple construction are incomparable to the traditional manual leveling, which can be used as the decorative surface course and wear～resistant base course.
Hydroxypropyl methyl Cellulose has an important influence on the water retention, consistency, and workability of self-leveling mortars. The right amount of HPMC keeps the moisture in the mortar for a long time. Hydroxypropyl methylcellulose has a retarding effect on the mortar. As the cellulose ether content increases, the setting time of the mortar is prolonged.
Hydroxypropyl methylcellulose has a strong influence on the bonding properties of self-leveling mortars. Hydroxypropyl methylcellulose enhances the plasticity and flexibility of the mortar, reduces the stiffness of the transition zone between the mortar and the substrate, reduces the sliding ability between the interfaces, and to a certain extent enhances the bonding effect between the mortar and the substrate.
Application to self-leveling function
1. Ensure the fluidity of the self-leveling mortar.
2. Improves the self-healing ability of the self-leveling mortar.
3. Helps to form a smooth surface.
4. Reduces shrinkage and increases load-bearing capacity.
5. Improves the adhesion and cohesion of the self-leveling mortar to the substrate.
